Your grass needs about 3/4″-1″ of water per week to maintain color and active growth.
- Summer
Some people water their lawn consistently as needed throughout the hot weather, or to let their lawn go dormant as conditions turn hot and dry, due to drought conditions sometimes you have to let it go dormant. Do not go back and forth, don’t let it go brown and then water it enough to green it up and then let it go brown again. Pulling it out of dormancy drains large amounts of food reserves from the plant. - Water infrequently
When you do water thoroughly water so moisture soaks down into the roots. Exception to this is a newly seeded lawn where the surface needs to stay moist. Avoiding frequent watering promotes shallow roots and some weeds like crabgrass. - Water as early as possible
Early in the day when the lawn is wet from dew is the ideal time to water. Avoid mid-day watering due to excessive evaporation during the heat of the day. Night watering gives an increased potential for fungus and diseases to get a foothold. The exception to this is when night temperatures do not go below 68 degrees, then it’s better to water in the early evening, providing you don’t have watering time restrictions. - Water the lawn uniformly
Due to variations in sprinklers patterns require overlapping to get uniform coverage. Use a container to measure different parts of the lawn to measure how much water is being distributed. Avoid flooding, or missing spots altogether. On clay soils and slopes watch for runoff, and reapply to allow for adequate watering. - Water conservation.
To conserve water mow your lawn higher than normal, limit traffic on the lawn to control soil compaction and avoid pesticide use. Don’t water streets or driveways, it’s wasteful. - Avoid overwatering
Measure how much water you’re applying, use a raingauge. Overwatering does more than waste water it also makes your lawn prone to pests, and adds to pollution of our water systems by adding to storm runoffs. By operating a watering system correctly, you can reduce your water bills, disease and pest problems, and maintenance requirements. - Monitor Rainfall
Don’t water if you are expecting rainfall. Keep track of the weekly rainfall and do not apply more water than absolutely necessary. If your lawn doesn’t get 1″ it won’t die.
